TRACK WRENCH Filed May 51, 1950 `A ttorney Patented Feb. 23, 1932 i mr GRAHAM, or Ionawnsrne'ron j manoir wmmcrr` u nppncatioirmea my 31, 1930. seal No. 457375.`

My invention relates to track Wrenches and more particularly to a Wrench device for bolting up rail joints on a railroad track. Certain objects'of the invention are to `pro- L vide a Wrench comprising a spacer bar with track engaging arms and a Worm shaft adapted for slidable, axial and rotary niovement with a wrench jaw whereby all the nuts of a rail joint may be either set up or re-` moved at one setting of the device as a Whole. Further objects are to provide adjustable clamp means for securing the track engaging arms to the track rails, means for connecting the ends of the spacer bar to the track ties, and means for reversing the direction of the rotaryand axial movement of the Worm shaft.

With the above and other objects n vievvr Which Will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying draw- Figure 1 is a view in perspective showing the application of the device;

Fig. 2 is a view in transverse vertical section of the same taken substantially on a broken line 2, 2 of Fig. l;

Fig. 3 is a detail view in central vertical section of the ratchet wrench portion of the device; y

Fig. 4 is a detail view in elevation showing the handle connection with the 'Worm shaft; and

Fig. 5 is a fragmentary view showing the rail engaging end of one of the track engaginc arms in engagement with a rail. j

eferring to the drawings throughout which like reference numerals indicate like parts, the numeral 5 designates a rail joint that is spiked to a number of ties 6 in the j usual manner. My device comprises a pair of arms 7 whose rail engaging end portions are each provided with a shoulder 8 and which end portions have a series of square cut teeth 9 on their upper edge portions. Said shoulders are adapted to t snugly against 0 one side of the rail tread and a clamping plate 10 is provided `with aslot `11 Which is adapted to slip over thejtoothed end portions of saidyarms and to rest between said teeth in snug engagement With the other side of the rail `tread as shown in detail `in Fig.` 5 ofthe 55 drawings.` Said= teeth and plate thus provide adjustablemeans whereby di'erent sizes of railsfmay be clampedbetween the platefand shoulder as will be understood'. Y i 1 The remote ends of the arms 7 are slightl 60 cur-ved downward andare each providedwit j a `hole 12 and said holes are adapted'ilto re'- ceive a pin lformedn end blocks 14. Said end blocks are secured in fixed spaced rela tionibyan upper and a lower spacer bar l5 65 I Whose end portions "are Welded; ibrazedd., or otherwise j `fixed tothe respective 1 under" and upper sides of said blocks'. Said end blocks Y are each provided witha hole passingupward'- ly: therethrough and through the end portions 7u ofthe spacerbars fiixed thereto lSaid holes are adapted to receive the shank or upright portions l'of claw members VWhose bottom ends haveia spike *point 17 and Whose odset orwhorizontal` portions118 are likewise pro- 75 vided With a points19 at their ends;` Thus when the points 'of said .claw `members are imbeddedgin the ties I6 lassshovvnrin thedrawings the devlce'as a' whole is braced inreadw mess forwork.; Said spacer barfmembers may lbe"l adjustably `positioned and secured on` the shank? `portions. of i said. claw members by means of set screws 20. 1

Said pawl has a central upstanding finger 30 and apush rod 81 hasits central portion connected through said finger andits ends extending exteriorly of said casing. A bow spring 32 engages said linger and is adapted to retain either end of the pawl in engagement with theiratchet, as will'be understood.

In the use of my device, assuming tlrat'same 1s connected to the rallyandfties'asshown.1n
